JOHN T. HAWKER, OF NEAR XENIA, OHIO.

GULTIVATOR.

Specification of Letters Ifatent.

Patented Nov. 28, 1911.

Application filed February 18, 1911. SerialNo. 609,362.

To all whom it may concern:

Be it known that I, JOHN T. HAWKER, a citizen of the United States,residing near Xenia, in the county of Greene and State Of Ohio, haveinvented certain new and useful Improvements in Cultivators; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in cultivators,for example, corn plows.

More definitely speaking, the improvements relate to a forward steeringmechanism consisting of a truck frame, steering wheels, etc., soconnected with the cultivator frame proper that said mechanism may bemanipulated by the rider of the cultivator.

The object of the invention is' to provide means for making a short turnof the cultivator in the field, thereby avoiding the tramping down ofthe standing plants, for example, corn, while driving the cultivatorback at the end of each row.

Before describing the invention at length, the accompanying drawings arereferred to as follows.

Figure 1 is a side elevation of a corn plow having my turning mechanismattached. Fig. 2 is a top plan view. Fig. 3 is a sectional elevation onthe line aa of Fig. 2, looking rearward.

In a particular description of the invention, similar referencecharacters indicate corresponding parts in the drawings, anddescription.

The parts of the cultivator proper consist of the usual triangular gangframe 1, which is pivoted at its forward end to a hanger 2 suitablyconnected to the upper longitudinal draft bar 3. The cultivator wheels 4are supported upon axles 5 extending down from a cross shaft 6,supported in a well known manner by brace bars 7 extending rearwardlyfrom the draft bar 3. The drivers seat 8 is supported in a common mannerupon the rear end of bar 9, which is rigidly secured to the draft bar.Treadle bars 10 extend down in proximity to the feet of the driver andsupport feet rests or stirrups 11. The cross beam 12 attached to thefront end of the draft beam 3 supports the usual swingletreeattachments. This is about all thatit is necessary to specify regardingthe old and well known parts of the cultivator running gear proper.

Referring now to the features embraced within the scope of my invention,13 is a cross beam secured rigidly to the draft beam 3. The ends of saidcross beam receive upright tubular members 14, the lower ends of whichare inclosed by collars 15 from which extend braces 16 united to saidcross beam 13. Projected through the tubular member 14 are upright rods17, the lower ends of which support two small front steering wheels 18.The ends of the uprights 17 extending above the upper ends of thetubular members 14, have attached to them crank arms 19 the outer endsof which are connected by a pivotal transverse connecting rod 20. Thesaid uprights 17 also have another set of cranks 21 connected to thembelow the said tubular members. The upper set of cranks compel the axlerods 17 and the steering wheels to move in unison. The lower set ofcranks have connecting rods 22 extending rearwardly therefrom, and theseconnecting rods are coupled with the treadle bars 10. In guiding thesteering wheels only one treadle is actuated at a time. For example, theleft treadle is instrumental in turning said wheels to the left, and theright treadle to the right. The facility for operating the said steeringwheels from one or the other treadle is due to the upper set of cranksand connecting rod.

Having described my invention, I claim:

In a cultivator, the combination with a frame, front and rear axles, thefront axles being extended upwardly and swiveled to with the lastmentioned cranks, substansaid frame, and wheels mounted on said tiallyas specified. 10 front and rear axles, of cranks at the upper Intestimony whereof I affix my signature, ends of said front axleextensions, a single in presence of two witnesses.

connecting link between said cranks, cranks JOHN T. HAWKER.
